Temperature-jump studies have been used to detect a rapid reaction in the thermal unfolding of ribonuclease A (RNase A). The fast reaction occurs over a wide range of pH, and the results of a detailed study at pH 1.3 are reported here. Although its amplitude is small, the reaction is easily measurable over the entire temperature range of thermal unfolding. It occurs in the millisecond time rang...

Background & objectives: Dyes are one of the main environmental pollutants of textile industrial wastewater which are toxic, carcinogenic, mutagenic, and non-biodegradable. Therefore, in this study, Response Surface Methodology (RSM) was used to investigate the operational parameters and determine the optimum conditions for the removal of acid blue 113 in the presence of bentonite. Methods: The...

The thermal degradation behavior and pyrolysis kinetic models of wood flour (WF)/PVC composites before and after adding chitosan were studied using thermogravimetry (TGA) and nine common kinetic model functions (f(α)). The results indicated that the thermal degradation temperature of WF/PVC composites was delayed to a higher value after adding chitosan. The first-order reaction order (L1) model...

The kinetic analysis of complex solid-state reactions that involve simultaneous overlapping processes is challenging. A method that involves the deconvolution of the individual processes from the overall differential kinetic curves obtained under linear heating rate conditions, followed by the kinetic analysis of the discrete processes using combined kinetic analysis, is proposed. Different con...
